Bricklaying - how much should this cost?

[Adsibob]

Foundations are already in place, and bricks are on site. Brickie would needs to mix and supply mortar. How much should it cost to do that and build the following walls (excluding pointing):

 

1) one single leaf brick wall in a straight line, 4m long and 3 courses high;

2) one single leaf brick wall in a straight line, 5m long and 2 courses high; and

3) one 9m wall, only one course, laid as a soldier course though bricks lying down as opposed to upright, has two 45 degree bends and one 90 degree bend (photo of a couple of bends attached so you get my meaning).
